Copyright OASIS, 2004 ebXML BPSS – mission profile Ability to create sharable industry process definitions Neutral approach not tied to specific middleware or transport systems Suitable for business analyst designers Support internationally agreed business process definitions and methods Provide the process details to direct implementation systems Support a variety of modelling methodologies

3. Copyright OASIS, 2004 OASIS ebXML BPSS in a nutshell BPSS schema defines components used to define the process models Original foundation derived from UML techniques Support for workflow as well as activity diagramming Foundation around business transaction definitions and interchanges Binary-collaboration and Multi-party interactions

10. Copyright OASIS, 2004 Documents and Transactions Determine the interchanges involved in your business process Label those transactions accordingly Specify the detail of the actual document formats involved Determine success and failure criteria and how these get notified Note any context parameters that might apply from those business interchange details Select the transport level profile to use

11. Copyright OASIS, 2004 Build interchange details Create headers for each of your transaction exchanges

12. Copyright OASIS, 2004 Enter the document formats needed Create document definitions and select type of identification

13. Copyright OASIS, 2004 Add document links to transactions In Transactions area add initiating and responded documents Initiate Transaction Provide Responses

14. Copyright OASIS, 2004 Configure Fail / Succeed conditions BPSS provides set of default conditions that marry to transport layer (ebMS) responses and outcomes

15. Copyright OASIS, 2004 Setup Business Exchange Profiles Convenient profiles – pre-configured with typical interchange characteristics, and linked to the failure / success outcomes

16. Copyright OASIS, 2004 Summary – configuring Transactions Select behaviours from profiles, conditions and transport needs Configure Exchange Details

17. ebXML BPSS V2.0 Copyright OASIS, 2004 How do we provide standard industry domain processes, but then be able to apply local criteria to those? Business Context Mechanism

18. Copyright OASIS, 2004 Context is the pervasive driver to effective engineering Drives dynamic process configuring and control Ensures accurate information capture, packaging and delivery Key to correct relationships between partners in a collaboration Lack of context control mechanisms is the most prominent reason why legacy e-Business systems are difficult and complex to extend and support Date: circa 1568 1 : the parts of a discourse that surround a word or passage and can throw light on its meaning 2 : the interrelated conditions in which something exists or occurs Understanding about Context

20. Copyright OASIS, 2004 Generating a Context Instance Add parameter value rules and document value rules Check a document and change a BPSS parameter Create a rule and set a value Configure Context Instance header

23. ebXML BPSS V2.0 Copyright OASIS, 2004 Worked example – completing the BPSS template Modelling the Process Flow

24. Copyright OASIS, 2004 Summary of steps required So far we have defined the: – Transactions – Documents – Success / Fail criteria – Transport exchange profiles – Context parameters Now we have to complete the picture by building the actual activity flow

25. Copyright OASIS, 2004 Start the Action Processes Add Start block and beginning Transaction action Assign Transaction Assign Roles to participants Configure BPSS header

26. Copyright OASIS, 2004 Next add responding action details Responding block consists of success / fail actions Select associated responding document Group Possible Responses Configure outcomes and flow control Transport layer return settings

27. Copyright OASIS, 2004 Decide next action details Request continues based on what responder does Next action Fork on outcome and pick next action, conditions gated by “beginWhen” conditions on Transaction Process Completes

29. ebXML BPSS V2.0 Copyright OASIS, 2004 Sharing Models Supporting Versioning and Tool integration Targetting deployment engines Part 3 – Editor Deployment

30. Copyright OASIS, 2004 Sharing Models The BPSS models can be shared in a variety of ways – – Save As : JPG, GIF, BMP, PNG, etc graphic – Generated to XML – Published to web via built-in web folder system – Saved in Registry – Can create library of pre-built components for a community

31. Copyright OASIS, 2004 Supporting Versioning and Tools The XML syntax used to generate the BPSS model is stored externally from the model itself #include instructions retrieve syntax when the model is generated Replacing the XML syntax files and regenerating the model automatically creates latest syntax Multiple output scripts can be defined – so one model can output BPSS V1.05, BPSS V2 and also some other target syntax such as jBPM for JBOSS, or a vendor specific flow control syntax.

32. Copyright OASIS, 2004 Targetting Deployment Engines Whenever BPSS functional behaviour can be simulated by equivalent syntax used by a deployment engine – that syntax can potentially be output from the BPSS model The BPSS model and approach is neutral to the middleware layer If the middleware layer is using ebMS transport this emulation is likely to be especially straightforward Integration to WSDL based steps also is supported

34. Copyright OASIS, 2004 Summary: The Holy Grail of e-Business Automatic information integration has been the Holy Grail of e-Business systems since before XML was conceived. Lesson learned - three needs are paramount: – the ability to design transactions and processes consistently, – the ability to document their usage in a clear way and then – the ability to drive software that can apply rules and test information context to configure dynamically to local needs
